Default Transmission not shifting

Hello I have a 2003 ram 1500 2wd. It won’t shift gears after 2nd. When we scan it the codes are as followed
0551 power steering pressure sensor circuit range performance
0841 transmission fluid pressure sensor / switch A circuit range/performance
0700 transmission control system malfunction
0733 gear 3 incorrect ratio
0734 gear 4 incorrect ratio
0735 gear 5 incorrect ratio
0440 evaporative emission control system malfunction
0456 evaporative emission system leak detected very small leak.
What code my issue be?

I would check and see if the various pressure sensors are getting the correct input voltage......

That list of trans codes, my friend is the RFE kiss of death. Your OD clutches are gone from either too much in and out of OD or too many full throttle kickdowns. 2P (kickdown gear, different from regular 2nd) uses the same clutch pack as the OD gears (4th & 5th) and are the physically weakest ones in the case. Replace or rebuild.

When I dropped the pan to change the fluid I didn’t have any metal in it at all.

HeyYou is on the right track. Unless you have codes you have been ignoring for awhile, you have too many codes for this to be just a transmission problem.
DodgeForum has kindly put the service manual and wiring diagrams for this truck here: https://dodgeforum.com/forum/2nd-gen...e-manuals.html
You'll note that the Transmission Control Module, Evap Control, and Power Steering pressure sensor share a common ground. TCM handles all the functions of the transmission. You may very well have a power supply/ground problem, not a mechanical problem. Electrical problems seem to cause cascading trouble codes. Before you pull a transmission for overhaul, try fixing the other codes first.
If you are not comfortable with wiring diagrams and chasing down power, voltage drops and such, you'll need a mechanic to help. Don't start throwing parts at this until you are sure.

69_XS29L now that you mention potential electrical problems my truck battery seems to do quite often like something is drawing power constantly somewhere. My grandfather was a electronics technician so I’ll show him the diagrams. Thank you so much.

My apologies, have a digital '03 you all are welcome to. Have the complete printed set of Powertrain, Body, Chassis, Trans Diagnostics if a scan would help.
